IMPROVEMENTYIN FEATHER-RENOVATING MACHINES.

Specification forming part of Letters Patent No. 185,824, dated January2,'1877; application tiled August 18, 1876.

To all whom it may concern Be it known that I, ISAAC L. FISHER, ofHamilton, Butler county, Ohio, have invented a new and usefulImprovement in Feather- Benovating Machines; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference'marked thereon.

Figure 1 representsa perspective View of my machine with portions of thecasing removed. Fig. 2 represents a central vertical section. Fig. 3represents a central horizontal section. Fig. 4. represents a verticalsection of the lower half ofthe machine, taken at the dotted line ofFig. 3. Fig. 5 represents a horizontal section, showing the interior ot'the upper half of the machine.

My invention consists in an improved construction and arrangement of thesteam and air conduits used in combination with the chest or cylinder inwhich the feathers are v steamed, cleansed, and dried, as hereinafterdescribed.

The chest or cylindrical receptacle A is supported upon legs a, and itslower half is double, having the interior casing B secured therein, soas to form a steam-tight chamber, P, with which the ingress-pipe b andegress-pipe c communicate. The perforated pipe D, for injecting thesteam from a suitable boiler among the feathers within the chest, isarranged centrally upon the interior casing B, as represented; and anegress-pipe, d, communicates with the chest through the intermediateperforated screen E at the top of the machine.

To provide for the passage of currents of air through the machine, thedepressions Gr H are made in both the outer and inner casings A B at thebottom of the machine, and the depression H is covered with perforatedsheet metal, through which air will be forced into the chamber in whichthe feathers are placed, at the proper stage of the work, for drying andcarrying 0E dust`and impurities. The

air-induction pipe J enters the steam-drying chamber P between thecasings A B, and passes into the depression H, under screen M, andaround its sides, as indicated by the dotted lines in Fig. 3, and asthat portion of pipe J which enters the division H is perforated,

the air will be distributed, and pass up through screen M into thechamber in which the feathers are placed for cleansing.

The crankshaft G is armed with beaters for agitating the feathers duringthe steaming and drying operation.

A drum connected by a trunk, K, with the division at the top of themachine, formed by the perforated partition E, is provided with a fan orblower, L, for drawing air through the machine.

Instead 0f the fan at the top of the machine, a fan or blower, A', maybe used in connection with the air-induction pipe J, which will forceair through the perforations in plate M, thence up through the body offeathers in the machine, and thence out through perforated partition Eand the egress-pipe d.

By the use of either of the blowers air will be driven through themachine for drying the feathers and separating and conducting away thedust and impurities which are commingled with the feathers, and whichhave become detached therefrom by the steaming, beating, and dryingoperations.

By the use of my improved apparatus for renovating feathers it isapparent that they may be disinfected by fumigation.

In using my machine the pipes b D will be connected with a steam-boiler,each having a stop-cock to regulate the admission of steam. In the firstplace, after the feathers are introduced through a door, N, the airingress and egress and the steam-induction pipe b will be closed, whilethe steam is admitted among the feathers through perforated tube D,during which time the revolutions of the shaft G with its beaters willcause a thorough agitation of the feathers, and the steam will find itsexit through pipe d. After the feathers have been acted upon by thesteam sufficiently the ingress-pipe D will be closed, and, as thecondensation of the steam progresses within, steam will be admittedthrough pipe b into the drying-chamber P, which surrounds the lower halfof the feather receptacle or cylinder.

Suitable pipes for drippings, as indicated at c f, are connected,respectively, with the division H and the drying-chamber P. These pipes,as well as the air and steam induction and eduction apertures, must havesuitable cnt-off slides or cocks to properly regulate the work.

To facilitate the drying of the feathers while the beaters are inagitation and the chamber P is charged with a flow of steam, the belt XX will be placed upon its pulleys to set the fan in motion to cause theair to be drawn through the body of feathers, as herein specified; andas the air is forced up through the perforated plate M, that is overdivision H, it will be diffused thoroughly among the feathers, andgreatly facilitate the process of drying them, and at the same timecompletely cleanse them from offensive odors and impurities.

Having described my invention, I claim and desire to secure by LettersPatent- In the feather-renovating machine provided with thedrying-chamber P, air-division H, and partition E, the combination ofthe steam and air conduits b, c, D, d, and J, substantially as and forthe purpose described.

ISAAC L. FISHER.
